    Great product!

    Product was as described, easy and quick to install. More robust build quality than the last different brand harness I purchased.

  • A REAL upgrade for Your car if You have voltage drop present at the light bulb sockets !

    This harness gives Your headlights new life. Practically no voltage drop at lamp sockets. My original harness measured 10,3 volts for the high beam and 10,7 volts for the low beam. It was like driving with candles in the dark night. This harness gave me a full 12,5 volts at the lamp sockets. Wires was cut to fit my chevy caprice 91` in perfect length. The ceramic lamp sockets can handle powerful light bulbs like 80/100W without getting burned.
